MPLS流量工程仿真

在通信网络中,负载不均衡或部分网络失效常常会引起网络拥塞问题,导致业务的服务质量下降.相对于传统的动态路由协议解决此类问题所具有的局限性,MPLS流量工程是解决问题的一种有效途径.在计算机网络仿真平台上,设计了动态路由协议和MPLS流量工程仿真实例,通过运行仿真,获取了它们的网络性能及业务服务质量数据.通过对仿真结果进行比较和分析,可以看出,MPLS流量工程通过更为灵活的方式在多条链路上实现负载分担,可以改进网络资源利用率,当链路或节点失效时,能够提供快速的恢复机制.

Simulation of MPLS Traffic Engineering

In the communication networks,network congestion issues are often caused by unbalanced loading or partial network invalidation,which will decline the quality of service.In contrast with the limitations of the traditional dynamic routing protocol for resolving the network congestions,MPLS Traffic Engineering is a valid solution to the problem.We design the cases with dynamic routing protocol and MPLS Traffic Engineering through network simulation,based on simulation,the data of the network performance and quality of service are obtained.The analysis and comparison of the simulation results show that MPLS TE can realize the load balance between many links in a more flexible mode.It can improve the network resource utilization.The fast resume mechanisms are also offered when the links or nodes fail to work.
